What is what are thunder beads used for?

Thunder beads are a type of sex toy used for vaginal or anal stimulation. They are typically long strings of small, round beads made of materials such as silicone, glass or metal. The beads are designed to be inserted into the vagina or anus and slowly pulled out during sexual activity to enhance pleasure and increase orgasm intensity. Some people also use thunder beads for solo play during masturbation. They can be used by people of all genders and sexual orientations. It is important to use lubrication and to clean the beads thoroughly before and after use to prevent infection or injury.
